Those 44s were shot out of a 10.5” Super Blackhawk.
Today I loaded a couple up in a 444 Marlin case and performed the same “test” with my Marlin 444P. I don’t know that I’ll use this as a 444 bullet. Penetration of 3.5” and 5” as opposed to about 6.5” with a 265 Interlock that is made for the 444. Expansion was pretty good though. Lol
Weight retention, not so much.
Compared to the 265 Interlock.
The two Zeros on the left and the Hornady Interlock on the right.
